A microwave emitter for use in a microwave sensor assembly that includes an emitter body includes a first arm that extends radially outward from the emitter body. The first arm is at least partially non-linear and includes at least one peak and at least one trough. The microwave emitter also includes a second arm that extends radially outward from the emitter body. The second arm includes at least one peak and at least one trough. The first arm and the second arm generate an electromagnetic field when at least one microwave signal is received.
